Almace is from my first completed Marathon (Infinity) fic, “Kingdom of One”. It’s old enough now that I guess I can just outright state who Almace is: the fusion of Durandal and Tycho who took on a new identity. Not the sort of person you want to get in the way of.

Double dose of naming appropriateness; first off Almace in the name of a sword that in some stories is part of the same set as Durandal but has been seriously overlooked by Bungie fans, and secondly it means "almighty" which is fitting given the probable size of his combined ego.
